(*) NOTE: This amplifier follows the ground
interconnection specification defined by AES48-
2005 standard of the Audio Engineering Society,
on grounding and EMC practices for audio
equipment containing active circuitry.
For that reason, when a source with unbalanced
outputs should be connected, it is recommended
not to use Pin1 of the XLR, and never connect it
to Pin3.

7 - OPERATION MODES

Stereo
In Stereo mode, each one of the amplifier channels
works independently. To select it, make sure that the
MODE selector, located next to the input section
(BALANCED INPUTS) is in the STEREO position (3
and 4 DIP switch OFF).
Parallel
In this mode, the signal inserted at CHA input will be
routed to both channel's power modules (CHA and
CHB), ignoring the signal at CHB input. This option is
useful when a series of speakers must be fed with the
same signal, because the signal can be routed saving
extra cable connections between inputs. To use
Parallel Mode, place the MODE selector switch in
PARALLEL (DIP switch 3 OFF, DIP switch 4 ON).
The corresponding indicator located on the front
panel will light up (PARALLEL).
Bridge (Mono)
In this position both channels are used as a single amplifier, capable of delivering the
double of the power. In this operational mode the input signal must be fed through
CHA input connector. At the output, connections must be made as following:
The + Pole of the speaker is connected to the Speakon Pin +1 of CH A, or the Red
terminal of the CH A. The – Pole of the speaker is connected to the Speakon Pin +2
of CH A, or the Red terminal of the CH B.
